So I'm trying to import a function from a library I'm developing. I have "libraryD.dll" built for debugging and "library.dll" for release. Unfortunately, that means that I have to do this:
[Code]...
Now this would be fine but for ALL 40 functions this would make things very ugly to look at (and a tad bit unfriendly).I would like to do something more like this:
[Code]...
Is there ANY way to do this in VB?
how would it go to be able to use in a VB application some statistical functions that are in Excel?
Basically I would just want to know the general lines of how something like that goes, what things need to be imported and so and whether this is a very complicated thing or rather it is just about importing stuffs. I have found something like this (which extends itself ) . I get tons of error red lines that never seem to end despite correcting using the options, new ones appear etc

I have this script that reads the accelerometer on my m200 tablet pc but I don't know how to use it in a windows form, how to import or declare it it would be nice.
The .cs script is

I know I can access the local Eventlog using build in functions. However, I need to be able to open and read evt and evtx files save on a remote computer for further analysing.
View 6 RepliesWe have a typelib where we define some constants. One of our sets of constants is created using the module keyword:
module MyConstants
{
const int Const1 = 1;
};
I use tlbimp.exe in a bat file to generate a primary interop assembly for internal use.If I create a VB .net project and add a reference and browse to the .tlb file and import it, the result I see in the browser window is a class named MyConstants. If I click the class, the right hand pane is empty - the class contains absolutely nothing.
If I add a reference to the primary interop assembly, I also see the class MyConstants int he browser window. When I click the class, the constants show up.This is in Visual Studio 2010 (RTM). Why does VB .NET add reference via brwose to the .tlb file differ in this case? Is this a bug in VB .NET or the tlbimp.exe tool?
I am running a program in windows forms visual basic and im trying to make multiple counters
Here is my code:
If txtAnswer.Text = nMathSum Then
nCount = nCount + 1
lblCorrect.Text = nCount
[code]....
It suppose to count how many times i answered correctly and incorrectly The Counter for the Sum is working fine but the counter for the difference has a problem. When i input the correct answer it goes to the incorrect label.
I usually always use enummerations as a pass ID of some type with a calculated value using the n^2 notation to calculate the return values. It's easy to derive with squareroots what values are derived from a sum; but most of the time I use the Identifier String to denote a combo box drop down list view. I think this is fairly routine for most developers; since in all my coding or rework I have seen it used commonly by other developers also.
Anyway, I wanted to do some sort of comparisson array of strings to fill the combobox using the *.Items.AddRange() function and it requires an array pass (this typically shrinks the code down considerably) and if you want to mix and match arrays in segments it's easier. So here is the code; for doing so I am assuming that other developers use an "AddToArray" type function like me; if not you have to write the function or just replace the code with the actual adding to array.
''' <summary>
''' Convert an enummeration to an array.
''' </summary>
''' <param name="ConvertTo">Convert to return type.</param>

I want to be able to have the user type in a function, say ,x^2 + 1, and have the computer store this such that it can be recalled and plug in a given value for x. For example, say they type in x+4, the program will then (in a bunch of different text boxes) return the value of x+4 when x = 1, x = 2, and so on up to x = 10. But how can I get it so that it will store x+4, be able to recall it and replace x with it's given value
View 2 RepliesIs there a way to build a new class during Runtime? Or at least, add a new property to an existing class.
I mean creating a class that doesn't exist and not an instance of an existing class. I could later on use reflections to load and use this class.
I am trying to do something, which I seems to be pretty simple, but no matter how I try, one thing or another doesn't seem to work. All I want to do is check if the current date is 14 days prior to an expiration date display how many days until the expiration date, but if the current date is past the expiration date, display an expiration notice.
If have tried a bunch of different ways, but none seem to work. Here is the latest variation that is not working:[code...]
What I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).
Is there any alternative to VB's CBool keyword in C#?
What about all the other functions?
CBool will turn to a Boolean any valid boolean: 0, "False", null etc.

View 2 RepliesI'm reading a tutorial provided by someone at my university, and it claims that if you're debugging a VB.NET program, you can hover over a conditional (e.g. "Age > 13") and it will be evaluated. However, in VB 2010 Express, I am not seeing this functionality.
I believe the tutorial may have been written for a previous version of VB.NET, so I was wondering if anyone could tell me if this used to work and has been removed, or whether it has never existed?!
I am able to hover over a variable and see it's current value, and I can even "Watch" an expression (such as the conditional), but the tutorial claims[code]...
I am interested in building a simple GUI window using VB.net that looks more or less like the Firefox download manager (press Ctrl + J when you are in firefox to see how the window looks like). However, instead of Search, I would like to have a text space where I can enter the download URLs.
So basically, initially, I have a blank window with a clear list button and a URL text box at the bottom, as I type in the download URLs and press enter on keyboard, the text area at the top shows the download file name as well as the progress bar.
One more thing I would like to add is to have the window to automatically resize itself, meaning the more jobs I added to a list, the longer the size of the window will grow, up to a certain limit.
This is my first attempt on coding up something on the GUI side, so I am just wondering if there is anything to get me start with, is there like a package or library to get me started? Or, obviously preferably, is there already a package of something like this in VB.net?
I am using VS.Net 2003. I have a solution that contains 4 projects. The first project contains the definitions of interfaces. The third project is using the interfaces defined in the first project. For the third project, I added a reference to the first project. But I'm still getting a build error
View 11 RepliesI have I text tab delimited file. in every line of that file at the same position in every row of the file I will have a bit that I would want to compare against 23 values (I will call them criteria). So if on every row the string I need matches one of tjhese values then that row will be written in File1.Txt if that value doesn`t match any of the criteria the whole row will be sent to File2.txt.
So far managed to get the original file written in the same format in a newly created file.
how to get the functionality I described working but am stuck with correct syntax.
Here is what I have so far:
Dim fs As New FileStream("C:Original.txt", FileMode.Open, FileAccess.Read)
RichTextBox1.Text = ""
Dim d As New StreamReader(fs)
[Code]....
Now I will need to declare every single row in RichTextBox1 as String then will have to get the bit I need will have to declare that as well(I will need from every row the string taht is between characters 96 and 104), also where do I keep the 23 criteraia values.
I have created a DEMO project to illustrated what I am referring to. I have a simple form, the button is set to Enabled False in the property inspector. When the user complete the form controls(fields) the button is Enabled. Everything seem to be working except the following:
When the user completes all the field, they must type twice in the MaskedTextBox for the button to be Enabled.
Even though there is no actual characters typed in the box because of it's restrictions, why do I need to type twice in the MaskedTextBox before the button is Enabled. Here is my code:
Public Class frmActivateBtn
Dim blnCheckName As Boolean, blnCheckPet As Boolean, blnCheckColor As Boolean, blnPhoneCheck As Boolean
Function turnTestButtonOn()
If blnCheckName = True And blnCheckPet = True And blnCheckColor = True And blnPhoneCheck = True

I am working on a VB NET project and had the strangest thing happen.I created a class file(just like a dozen or so I have already created). I wrote in the code to access it. The autocomplete found the class, filled it in and colored it blue, just as it should.But, when I run the app, I get a type is undefined error.
There is nothing in the class yet. And there is really no code to post..it is as straight forward as I described.I tried restarting VS; Deleting and recreating the class; Deleting the class and creating a new one with a different name.
Is there something in the VB NET configuration I can check to see if it is not being added somewhere?
I found the problem. I have 2 projects in one solution. They both share some classes that were trying to use my new classes. When I hit F5, both projects are compiled, and since I hadn't shared the classes with the second project, it errored.
So, now my question is changed; How do I specify to only build the specified Startup Project when debugging?
Planning on migrating from 1.1 to 2.0 framework.After doing the automatic vs 2005 migration, it did highlighted lot of lines: due to unused variables and functions with no return type..Is there a tool which can fix those unused variables plus function with no return types.

1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.

View 2 RepliesI am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?
I just created a simple application. I Builded that using build->build myapp. I got .exe of that application. i runned. all went fine. but when i closed that app, even after closing it is in memory. it is still running. how to deploy it properly?
